Sondage SharePoint PARTIE 2

Sondage SharePoint PARTIE 2,
                message sur la page de retour.


Et en SharePoint 2010, comment j'aurais écrit la même chose mais cette fois en bénéficent de EcmaScript de SharePoint 2010. Pour référence voici la partie 1

Chargement
Dans un premier temps je veux utiliser la librairie "sp.js".


CODE:
              ExecuteOrDelayUntilScriptLoaded(initialize, "sp.js");


Cette ligne de code permet de m'assurer que ma librairie est charger dans ma page avant d'initialisé mon traitement. Effectivement les librairies Javascript sont chargés dans la page de façon asynchrone. Cette ligne me protège.


CODE COMPLET
